Thanks for the pointer - I did not know that this page existed. In
general, is there some easy way to track changes to this page and the
R extension manual over time? It is difficult to keep track of the
best practices.
I'd also like to get clarification on "Packages should not write in
the users' home filespace, nor anywhere else on the file system apart
from the R session's temporary directory (or during installation in
the location pointed to by TMPDIR: and such usage should be cleaned
up)." - what is recommended practice for packages to maintain state
across instances? Operating systems have standards for where
applications can store settings (e.g. as described in
http://pypi.python.org/pypi/appdirs/1.2.0). Is it acceptable to for
packages to follow these conventions?
The policy is meant not to overwrite user data or generate loads of
temporary files from examples and pollute, e.g., the owkring directory.
